Beskrivelse
In the present study, activated carbon is fabricated from male and female date palm leaves by chemical activation with phosphoric acid and is further examined for ferric ion removal from waste water. The study revealed that the uptake of ferric ions from aqueous media was found to be dependent on pH, adsorbent dosage, initial concentration, agitation time and temperature. The maximum adsorption capacity for male and female activated carbon was found to 17.2 mg/g and 22.2 mg/g respectively. The optimum conditions for ferric ions uptake from aqueous media by male activated carbon was found to pH=2.5, temperature=298K, initial concentration= 50 mg/L, adsorbent dosage=0.2 gm and agitation time=30 minutes. Similarly for female activated carbon optimum conditions were found to be pH=2.5, temperature=298K, initial concentration= 50 mg/L, adsorbent dosage=0.25 gm and agitation time=30 minutes.
